2 objects moving irraticaly very high in the sky over winnipeg. Higher than satellites that I usually see. Moved at various speeds and directions within the space of the big dipper as seen from south winnipeg. Moved north from the last star on the handle and back to the star on the bottom of the dipper bucket then south and back west speed ranged from slow to very fast and not in straight lines. These craft were very high. I frequently see satellites and the space station but these were far higher and only visible as dots. They were not aircraft.
